Define architecture, module configuration, and enclosure design ensuring compliance with safety, performance, and reliability standards.
Develop CAD models, drawings, and BOMs for pack/rack assemblies.

Technical Leadership

Guide cross-functional teams (mechanical, electrical, thermal, controls) in design reviews and decision-making.
Establish design standards, best practices, and validation protocols.
Mentor junior engineers and foster a culture of innovation and collaboration.

Safety & Compliance

Ensure designs meet international standards (UL, IEC, IEEE, NFPA, etc.) IEC 62619, UL 1973, UN 38.3, IEC 62620, IEC 61000, IEC 60529, QM 333, IATF 16949, ISO standards. for electrical safety, fire protection, and mechanical integrity.
Integrate safety features such as thermal runaway mitigation, fault isolation, and protective housings.

Integration & Testing

Collaborate with system engineers to integrate packs into overall BESS solutions.
Oversee prototype builds, validation testing, and qualification processes.
Troubleshoot design issues and implement corrective actions.

Project Management

Manage design timelines, deliverables, and resource allocation.
Coordinate with suppliers and manufacturing partners for component sourcing and production readiness.
Support cost optimization and scalability for mass deployment

Knowledge and connect with the relevant vendors and subcontractors for all the design support activities such as mechanical fabrication, Laser welding etc

Required Qualifications

Bachelor's / Master's/ PhD degree in Mechanical Engineering, Electrical Engineering, Battery Chemistry or related field.
